Physiologic and performance effects Amphetamines increase dopamine/norepinephrine release and inhibit their reuptake, leading to central nervous system (CNS) stimulation Amphetamines seem to enhance athletic performance in anaerobic conditions 39 40 Improved reaction time Increased muscle strength and delayed muscle fatigue Increased acceleration Increased alertness and attention to task 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 "Adderall XR- dextroamphetamine sulfate, dextroamphetamine saccharate, amphetamine sulfate and amphetamine aspartate capsule, extended release"

In the in vivo experiments, the authors treated the streptozotocin-induced DM mice with exendin-4 at 10 nmol/kg for 4 weeks and found that exendin-4 promoted the peripheral nerve function as reflected by improved current perception threshold and motor and sensory nerve conduction velocity
How age-related declines in VO max constrain healthspan and everyday physical function [12:30]
Peptide integrity is too critical to guess
That upper limit is designed for unsupervised long-term population usenot for every medically monitored treatment situation
